The Back It Up is a unique vibrating plug and ring combination! The two powerful motors work together in the shaft and base for sensational and complete stimulation. The adjustable arms offer 3 different positions, while the bulbous plug tapers with a secure base to keep it perfectly in place. The material is ultra-soft silicone and can be used with a water-based lubricant. Thanks to the wireless remote control, you can enjoy hands-free operation with 10 delightful vibration modes and patterns from 2 motors, which can only be controlled together. The Back It Up comes with a magnetic USB cable and a wireless remote control with 1x CR2032 battery. The design is waterproof and can be cleaned with lukewarm water and a toy cleaner.
